WATER-WALKING DEVICE.

Application filed March 10, 1928. Serial No. 260,718.

This invention relates generally to walking devices, and has more particular reference to a novel water walking device.

The invention has for. an object the provision of a device of the class mentioned which is of simple durable construction, desirable and eflicient in action, and which can be manufactured and sold at a reasonable cost.

The device is for attachment to persons intending to walk thru a stream or body of water, of a height commonly walkable. It consists of a wedge member provided with straps for attachment to a wearer for cutting the water upon forward motion.- In conjunction with this, pairs of vertical plate members pivotally connected along front Vertical edges are mounted upon the wearers legs in such fashion as to resist backward motion of the wearer, and not to materially effect forward motion of the wearer.

For further comprehension of the invention,and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in'which the various novel features of the invention are more particularly set forth.

Referring to the accompanying drawing, forming a material part of this disclosure:

Fig. 1 is a perspective view of the device applied to a person.

Fig. 2 is a lan view of the wedge structure for cutting tie water upon forward motion.

. Fig. 3 is a plan View of the plate member structure in collapsed position, not materially effecting forward motion of the wearer.

Fig. 4 is a plan view thereof in extended position for resisting backward motion of the wearer.

Fig. 5 is a fragmentary vertical rear end View thereof, showing the hinge of the plate members in detail.

Fig. 6 is a vertical rear end view of a support for the plate members of the device, constructed according to modified form.

Fig. 7 is a plan view thereof.

The reference numeral 10 indicates generally a person provided with the device, and intending to walk thru a stream or body of water of a height slightly below the shoulders.

A pair of wedge members 11 are held in wedge formation by angle clips 12 and screws 13, and at the rear ends have lugs 14. A strap with buckles 16 are secured to the lu s 14 for attaching the wedge members to the ront of the person 10, preferably at stomach height.

An inner strap 15 is buckled at 16 to securely hold the wedge members.-

Support blocks 17 have front concaved sides 18 to fit the legs of the wearer, and are provided'with straps 19 having buckles 20 forattaching same to the wearers legs, at the backs or calf portions. Bars 21 are attached to and project from the center of the rear side of the support blocks, and the extended ends of these bars terminate in tubular members 22.

Each of the tubular members 22 engage in a cutout 23 in hinge 24 so that the hinge pin 25 passesv thru the tubular member. A pair of vertical plate members 26 are pivotally connected along their front edges by being secured to the hinge 24 by the screws 27.

Eyes 28 project from the sides of the block 17 and other eyes 29 project from the sides of the plates 26, and chains 30 are attached. to these eyes for restraining'the plate 26 from completely closing uponeach'other. Fig. 3

shows the plates closed as far aspossible,

while Fig. 4 shows the plates fully extended so as to lie in one plane, and abut'against the rear. face of the block 17.

V In Figs. 6 and 7, the block.17"is formed with a vertical slot 30% in its rear side, and vertical slots 31 in its ends. A left hand screw 32 is vertically and rotatably mounted in the block and communicates with slot 30*. The bar 21 with tubular member 22 at its outer end for sup-porting the hinged plates 26 is slidably arranged in the slot 30 and has an enlarged rear end 33 threadedly engaging screw 32. Right hand screws 34 are vertically and rotatably mounted in the block, and communicate with slots 31. The eyelets 28 for holding one end of the chains 30 are integral with rods 35 slidably arranged in the slots 31 and threadedly engaging the screws The screw 32 has a gear 36 near its bottom end, meshing with gears 37 on screws 34 and is also provided with a projecting square head 38. The head may be turned to raiseclosing to the position shown in Fig. 3 as the person moves forward relative to the water, so as not to interfere with forward motion and opening to the position, shown in Fig. 4:

as the person moves backwards relative to the water so as to restrain this backward motion.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is:

1. A means for not materially effecting relative forward motion in water, and resisting backward motion, comprising a block support, a bar attached to and projecting from the rear side of the block support, and terminating in a tubular member, a hinge with a cutout for accommodating the tubular me1nber, the hinge pin of the hinge passing thru the tubular member, a pair of vertical plate members pivotally connected at their front ends by being secured to the hinge and means for preventing the plates from completely closing, consisting of chains secured between the plates and the support block, the said bar being of such length to cause the plates to abut the rear face of the block support in entirely opened positions, for restraining opening further than aligned positions.

2. A means for not materially effecting relative forward motion in water, and resisting backward motion comprising a block support, a bar attached to and projecting from the rear side of the block support, and terminating ina tubular member, a hinge with a cutout for accommodating the tubular member, the hinge pin of thehinge passing thru the the tubular member, a pair of vertical plate members pivotally connected at their front ends by being secured to the hinge and means for preventing the plates from completely closing, consisting of chains secured between the-plates and the support block, the said bar being of such length to cause the plates to abut the rear face of the block support in entirely opened positions, for restraining opening further than aligned positions, and means for raising or lowering the plates rela tive to the block.

3. A means for not materially effecting relative "forward motion in water, and resisting backward motion, comprising a block support for attachment to ones leg, a tubular member supported on the rear side of the block and slightly spaced from said rear side, a hinge with a cutout tor accommodating the tubular member, the hinge pin of the hinge passing thru the tubular member, a pair of vertical plate members pivotally connected at their front ends by being secured to the hinge and means for preventing the plates from completely closing, consisting of chains secured between the plates and the support block, the said plates abut the rear face of the block support in entirely opened positions, for restraining opening further than aligned positions.

In testimony whereof I have affixed my signature.
